Detailed Description

template<typename PointInT, typename PointOutT>
class pcl::MomentInvariantsEstimation< PointInT, PointOutT >

MomentInvariantsEstimation estimates the 3 moment invariants (j1, j2, j3) at each 3D point.

Note:: The code is stateful as we do not expect this class to be multicore parallelized. Please look at NormalEstimationOMP for an example on how to extend this to parallel implementations.
